| Research Abstract |
Through International collaboration, we conducted ecosystem monitoring over subarctic North Pacific using Continuous Plankton Recorder (CPR) and archived plankton data set for 2001-2014. We studied the link between North Pacific Decadal Oscillation (PDO) and spatio-temporal variation of the lower torophic level ecosystem. Our analysis on plankton community structure revealed the mechanism how PDO-related seasonal and/or interannual variations in physical environments, such as sea temperature and vertical water mixing, significantly influenced timing of phytoplankton seasonality and size structure of zooplankton community. We also contributed to the establishment of Global Alliance of CPR Survey (GACS), which are operating CPR survey in various areas including North Atlantic, Southern Ocean, etc. Through the activities of GACS, we expanded the CPR network world wide to enable us to conduct global comparison of long-term marine ecosystem change.
